Sharp succeeded the production of high performance LCD using IGZO for the first time in the world. With the extraordinary TFT characteristics, IGZO-TFT LCD can realize (1)lower power consumption and (2)higher touch panel performance than a-Si TFT LCD. In this paper, we report the development of IGZO-TFT and new LCD devices.

We succeeded in G8 factory for mass production of Indium-Gallium-Zink-Oxide thin-film transistor (IGZO-TFT) for the first time in the world. The initial TFT process was an etching stop-type TFT, but now, we are mass producing channel etching-type TFTs. And, its application range is smartphones, tablets, PCs, monitors, TV, and so on. In particular, because of recent demands for high-resolution and narrow frame, our IGZO display has been advanced in technology development with gate driver in panel. In this paper, we report development combining low resistance technology and the latest IGZO-TFT (IGZO5) for large-screen 8K display.
